There’s nothing like having a shower to get ready for the day or indulging in a hot bath while relaxing before bed at night. But while the hot and steamy atmosphere might feel great for us, it isn’t so great for our bathrooms. 

A lack of ventilation plus all that warmth and moisture increases the likelihood of mold and mildew developing. Mold isn’t just unsightly; it can cause health conditions and trigger existent allergies. 

Purchasing an air purifier is a great investment if you want to minimize such health hazards and breathe cleaner air while having your shower or bath. It will also help to eliminate those unpleasant bathroom odors.

The best purifiers contain true HEPA/H13 filters. These capture the greatest number of harmful airborne particles, even the most microscopic ones, reducing the growth of bacteria and the spread of toxins. Similarly, activated carbon or charcoal is excellent for helping to eradicate smells.

Before you buy a bathroom purifier, it’s helpful to consider many things such as:

  • Noise levels
  • Energy consumption
  • Design of the unit

Be sure to pay specific attention to your budget and room size as well. The CADR (Clean Air Delivery Rate) of a system lets you know how much square footage it will clean per hour. The Medify MA-40 is designed for large rooms and cleans 800 square feet in 30 minutes. But if you’re looking for something to use in a smaller bathroom, the Partu BS-03 is suitable for areas of up to 110 square feet.

To ensure we found the best bathroom purifiers to meet your needs, we used consumer reports analysis to guarantee that all our recommendations came from genuine people like you who have used these models.

1. Medify MA-40

The Medify MA-40 works hard to eliminate pollutants in your bathroom through the use of two HEPA filters. Each filter is designed with three layers that allow them to remove up to 99.9% of airborne particles such as dust, bacteria, virus carriers, and mold. These are common invaders found in bathrooms, more so if the environment is humid or moist.

Working alongside the HEPA filters is the activated carbon filter. This focuses purely on absorbing and eliminating odors. It’s easy for certain smells to build up in the bathroom, especially in the case of hidden mold. As the carbon filter makes the bathroom more comfortable to breathe in, the HEPA filters will kill the odor-causing issues at the source.

Also, there are four fan speeds you can adjust so the purifier performs as powerfully as needed. There’s also a Sleep Mode function for quieter running at night if you don’t want to wake anyone. Additionally, the purifier has strong airflow, covering an entire room with ease thanks to the 360-degree air intake design. It’s safe to use around children and pets too thanks to the child lock function.

First is the pre-filter that handles larger particles like hair and pet dander, a must-have if you have a pet area in your bathroom. It’s washable as well to extend the life of the purifier. The second is the True HEPA filter that focuses on capturing the finer particles. This includes airborne bacteria and mold spores that are readily found in a moist bathroom.

Next up is the high-efficiency activated carbon filter. This neutralizes common household odors, especially the ones that can linger inside a bathroom, leaving the room smelling fresher over time. Additionally, the purifier is useful to run at night thanks to the optional night light feature. It can make those bathroom trips in the dark easier to manage.

Otherwise, you can set it on auto mode so that it will adapt accordingly to real-time changes.

When it comes to purifying the air, the unit features a True HEPA filter that captures up to 99.97% of airborne particles as small as 0.3 microns.

As it cycles the air throughout a room of the stated size five times an hour, it can reach every corner of most bathrooms with ease for wider coverage.

As it’s a smart air purifier, it features an air quality sensor that continually operates. It will adjust the fan speed itself depending on the detected quality. When run regularly, the air should be kept clean thanks to the True HEPA filter that will capture small particles like mold that can build up in a moisture-ridden bathroom. There’s also the deodorization filter to eliminate those nasty bathroom odors.

There’s good circulation with the unit too as it can create a noticeable difference in air quality in a room as small as a bathroom in just a few hours. It works hard enough to even combat pet odors if you have a furry friend that likes to hang out in the bathroom too.

6. PARTU BS-03

The PARTU BS-03 has a 3-stage filtration system that consists of a pre-filter, a HEPA filter, and an activated carbon filter.

FAQs About Air Purifiers for Bathrooms

Why should you have an air purifier in your bathroom?

Bathrooms are a prime area for bacteria and odors that can result from mold and mildew. This is because the room gets wet often due to moisture and steam from showers, and it stays that way for a long time after if it’s not ventilated well. It’s a hot spot, so to speak. The right air purifier can cut down on mold spores in the air, improving the air quality and eliminating odors at the same time.

Furthermore, bathrooms are also a hot spot for airborne bacteria and viruses, especially if someone in the home is ill. An air purifier with the likes of a HEPA filter can capture those microscopic particles, reducing them down so that the air is healthier.

What problems are caused by excessive moisture?

Excessive moisture is an indoor pollutant that can damage your health and your home. Moisture easily collects on walls, mirrors, and windows. This build-up can lead to mildew, mold, and even dust mites. When it comes to your health, this can trigger allergy and asthma-related symptoms.

As for your home, excessive moisture can cause rusting in metal components found in the room. There’s a chance that it can even damage wooden furniture. Since it’s common for moisture to collect on the walls in a bathroom, too much of it can lead to the wallpaper peeling or the paint chipping. Mold can even start growing in various areas such as on the floor around the toilet.

What other ways are there to tackle mold and lower moisture levels?

One of the first things you want to check in your bathroom is the ventilation. Without proper ventilation, it can be difficult to lower moisture levels in such a contained space as a bathroom. Not only that, but good ventilation can help with odor control too.

A reliable ventilation system works together with an air purifier in this case. An air purifier works on treating the symptoms of moisture build-up, but it doesn’t get rid of the moisture. However, combine it with a ventilation system, and you can control both the cause and subsequent symptoms.

Which Air Purifier is Best for You?

A bathroom can be a petri dish all because of excessive moisture. It leads to issues with mold and mildew, which can damage our health and create odors. A good way to control those problems is with an air purifier.

There are a few important considerations to think of when shopping for one though. For instance, since it’s going in your bathroom, size plays a role in whether it will fit or perform well. So, we hope that our product reviews help narrow your search so you find the right unit to properly clean the air in your bathroom.
